I have a couple purple tipped acro frags in my 120g. I either got them from my LFS or fellow reefers. When the frags were in the fish store tanks or in the other people's tanks, the purple tips were very pronounced. In my tank I see little to no coloration on the tips. One frag has been in there 4 months, the other a month and the third, a week. I wouldn't expect anything from the one that's been in there a week, but I would have thought I would see some color on the others. I have two 250W XM 20k Metal Halides and two 110W Super Actinic VHO's. Is it my choice in lighting that's the problem or is it something else? Opinions please. My params:
Temp.: 78.5 deg. F
Alk: 9.0 dKH
Ca: 410
Mg: 1255
PO4: 0.1
NO3: <5 ppm
pH: 8.23
S.G.: 1.025
Thanks
